Alex Rodriguez is bringing his own food to restaurants in order to watch his diet as he prepares for spring training in Florida. The Yankee slugger was spotted at the Mondrian Hotel pool in South Beach on Saturday afternoon having lunch with girlfriend Torrie Wilson. But A-Rod didn’t order from the menu — sources say he’s following a special high-protein diet and travels with a cooler of his own grub. Rodriguez was seen asking a waitress to heat up his special meal in the kitchen, while Wilson nibbled on the poolside cafe’s chips and guacamole. A-Rod’s rep declined to comment. On Friday night, he joined his Yankee teammate Derek Jeter at Michael Jordan’s 49th birthday party. Jordan’s fiancée, Yvette Prieto, organized a surprise dinner at Miami’s Forge restaurant, joined by Paula Abdul, who sang “Happy Birthday.” Rodriguez later partied with Jordan and Jeter at South Beach club Mokai. The athletes, all without dates except for Jordan, danced at a table near the DJ booth until 2:30 a.m.
